OIL SEAL SERVICE AND MOUNTING FLANGE
OIL SEAL SERVICE. Drain oil from crankcase. If the
crankshaft end is rusty or pitted, polish the crankshaft
with emery cloth so it will not damage the bearings when
the cover is removed.
Remove mounting bolts and slide seal protector-driver
tool (Part No. 670327) into the oil seal. If necessary,
tap edge of flange or cover lightly with a soft hammer to
remove cover.
Clean and inspect the cover for wear and scoring of
bearings. Inspect crankshaft bearings. Replace any
worn or damaged parts.

If crankshaft is out of engine, remove old oil seals by
tapping them out with a screwdriver or punch from the
inside. To remove a seal with the crankshaft in the
engine, insert a screwdriver between the seal and the
crankshaft and pry the seal out.
TO REPLACE SEALS: Lubricate the outside of the new
oil seal with oil prior to installation. Use seal driver-
protector tool Part No. 670327. Place oil seal over the
driver-protector and place over crankshaft, driving it into
position using universal driver No. 670272. The seal
will automatically be driven into the proper depth.
Torque flange bolts in numerical order as shown in
illustration. See page 41 for torque specifications.
